Abstract: The study guide reflects the order of preparation and inspection of heads, organs and carcasses, veterinary and sanitary expertise of slaughter products of cattle, pigs, wild commercial animals, poultry. Materials are included in the features of inspection of products of slaughter of horses and some other animals. Special attention is paid to branding and technological marking of carcasses and skins at the slaughterhouse enterprises.

Science
- Revealed that sarcocystis affects many species of farm animals and domestic and wild birds. The characteristic of the affected animals is given. Commodity, organoleptic, physico-chemical and microbiological parameters of meat of domestic and wild ducks affected by sarcocystis were defined.
- Discrepancies in the veterinary and sanitary assessment of meat in some diseases, identified during the slaughter of animals were defined. It is recommended to make additions to the new Russian “Rules of veterinary inspection of slaughter animals and veterinary and sanitary expertise of meat and meat products” taking into account the veterinary and sanitary evaluation of slaughter products approved in foreign countries, which will optimize the veterinary requirements for slaughter animals, raw meat and ready-made meat products.
- Regularities of growth and egg chickens of the cross “Shaver 2000” were defined, patterns of change in the thickness of mucosa, submucosa, muscular and serous membranes of the posterior intestine taking into account the age, phases, and phase of definitive development were described for the first time.
Scientific interests
- Veterinary and sanitary expertise;
- Age morphology of animals;
- Increase productivity of farm animals;
- Symptoms of pre-slaughter and post-slaughter diagnosis of diseases of farm animals.
Meat productivity of calves and castrates of the red steppe breed under 18 months of age in 5 ages was studied: 1 day, 6 months, 9 months, 15 months, and 18 months, with the average daily live weight gain of 820 g and 775 g, grown and fattened on own feed. The calves were castrated at the age of 3 months. By the age of 18 months, the calves gained live weight of 475.2 kg, castrates - 444.25 kg, the carcass weight was 237.9 kg and 224.0 kg. The slaughter yield of calves was 50.21% to 53.63%, and that of castrates - 48.83% to 55.25%. The carcasses were dissected with extraction of muscular, adipose and bone tissues, followed by weighing on scales. The relative weight of the muscle tissue increased in carcasses of calves from the age of 1 day till the age of 6 months from 64.02% to 71.27%, and then it decreased to 67.62% in the age of 18 months. In the carcasses of 6 months old castrates, it was 71.10%, and further decreased to 64.93%. The absolute muscular tissue weight growth rate in 18 months old calves, compared to that of one day old ones was 19.29 times, fat growth rate was 142.47 times, and bones’ growth rate was 11.29 times; in castrates in the age from 6 to 18 months - 2.84 times, fat tissues - 15.33 times, and bone tissues - 2.50 times. We believe that the absolute live weight in calves and castrates by the age of 18 months has not reached the biological growth potential due to unnormalized feeding.
The article presents findings of investigation of domestic and wild ducks carcasses to determine the extensity and intensity of affecting them with sarcocystosis as well as learning the basic symptoms of pre-slaughter and post-slaughter diagnosis of disease. The authors determine also marketability, organoleptic, physical, chemical, and microbiological indicators of domestic and wild ducks meat affected by sarcocystosis comparing it with healthy poultry meat. In recent decades, sarcocystosis became widespread in both animals and poultry.
It is revealed that sarcocystosis affects many species of farm animals, as well as domestic and wild poultry. The affected animals are characterized by reduced fatness and deteriorated consumer properties of meat, as the water content in the meat becomes higher at a smaller amount of protein, fat and extractive substances.
